Edit: Solved! See solution in comments

I’ve setup a self hosted lemmy docker and it works when accessing directly on the same subnet.

I don’t have ports opened in my firewall and my ISP don’t offer static IP so I rely on Clouflare tunnel as an alternative.

I’m able to load the front page, but can’t sign in. I don’t cache JavaScript through Cliudflare so I believe it’s relating to Websockets, but curious if anyone else has been able to get this working?
